That can be easily fixed:def sublist(lst1, lst2):s1 = ','.join(map(str, lst1)) s2 = ','.join(map(str, lst2)) return False if s2.find(s1)==-1 else True I don't know about best, but it works for the examples given.
For numbers, it will always work. But what about lst1 = [",",",,"] lst1 = [",",",",","] -- http://mail.python.org/mailman/listinfo/python-list
